The other green is a glitch. It's happened to me before. Some people see the same as you do, some people don't. I'm sure the other Green is called... "Fortegreen" It's just a little glitch, perhaps Innersloth will take care of it
If u look closely the player is fortegreen for a sec when they join, if a player is fortegreen in-game and they do medbay scan it is the same as red, fortegreen means bad connection
i had that twice in a row with my friend, he was orange, i was red.
first game: another orange.
second game: another red.
a couple games later: ANOTHER SECOND RED.
